I have a system which looks like this:
Tomcat Server (has haproxy installed and balances my proxy servers) >> squid proxy server >> outside. This is the connection flow. My tomcat instance stores ssl certificates which are used for https transmission to clients. I'm using a connect method in squid in order to not have to decrypt/encrypt the transmission from tomcat>client.
But some of my clients are not accepting CONNECT requests.
What can I do in this case if I want the squid proxy to be transparent and not have to decrypt/encrypt the transmission but also not send CONNECTs to clients. Thanks
This is my squid config:
